I want to chime in on this. From my understanding a doctor legally can do anything they choose to do. They have to follow a code of ethics that they swear by when they get licensed as an md. So they can face reprucussions such as losing their license if they do things that are not considered ethical. In the case of online doctors writing scripts, they can legally and ethically do this but it would be considered unethical to write scripts for controlled substances for a patient they have not seen in person. So online doctors do exist, and can write scripts, but you won't get any controlled substances this way. Just for a point of reference I see my Pdoc on a regular basis via phone consultation because I do not live where his office is, and he does write scripts for me.
